This is a precision milled filing guide that is used to simplify, and perfect, many of the grinding and filing chores needed in knife making. Using this tool, you can create perfectly even bevels on both sides of a blade, create accurate grip serrations on the top/bottom surface of any blade, create precision tang widths and flush joints for marrying guards and/or bolsters, and can be used for creating fine angles for artistic file working treatments. To use this tool, start by clamping the blade between the jaws of the file guide. This enables you to precision file both sides of the blade evenly using hand files or even a grinder. The benefits are enormous, as blade bevels start evenly, stick tang shoulders are squared, and hand file angles are much more accurate.

This tool is made from non-magnetic stainless steel and has carbide contact surfaces (HRC 78) to maximize long performance life. It will not rust when dunked in water (when cooling blades during grinding) and will not stick to steel dust during grinding. The contacts faces are protected by carbide strips (only diamond or other exceptionally hard tools will scratch these). These contact strips are 78 HRC and very hard. (Please note, ceramic belts can and will damage carbide.) This tool is designed for use with hand tools, or standard aluminum oxide belts (if using a grinder). The carbides are 5/32 inches thick and can be replaced if needed. The carbide strips are recessed slightly into the stainless steel base plates for added protection. This way the strips will not be knocked off, or be placed under pressure when clamping a blade in the file guide.

This precision tool accepts up to 2.75 inch wide blades (70 mm), and up to 1.6 inch thick blades (40 mm). It comes with hardened steel guide pins and (2) Allen wrenches for adjustment and maintenance.
